Steroid nasal sprays rarely cause side-effects. This is because they are applied directly to the nose and very little of this medicine is absorbed into the body. Therefore, they are much less likely to cause side-effects in other parts of the body. Occasionally, they cause dryness, crusting, and bleeding of the nose. If this occurs, stop it for a few days and then restart. There have been reports of nasal steroids possibly having an effect on behaviour, particularly in children. This is thought to be rare. However, a few people have reported hyperactivity, problems sleeping, anxiety, depression, and aggression.
For individuals allergic to cat or dog dander who are themselves pet owners, no avoidance strategy can approach the benefit that will be gained with elimination of the pet from the home. 15 In view of emotional attachments that commonly occur with pet ownership, as well as the potential therapeutic value of pets that may exist, 16 the decision to advise removal of a pet from the home must be discussed openly with allergic patients and considered carefully from an individualized risk/benefit standpoint. If a cat or dog is removed from the home, it must be recognized that due to persistence of the allergen for periods of several months, clinical benefit may not occur promptly. When elimination of pets from the home is not possible, second best measures include restricting the pet from the allergic person's bedroom, use of high efficiency particulate or electrostatic air cleaners, and removal of carpets and other upholstered items which otherwise serve as a reservoir for allergen. 15 Although allergen reduction may be transient and the potential for clinical benefit has not been clearly established, bathing the pet (cat or dog) may also be attempted as a "second best" alternative to elimination of the pet from the home.
It can take several days for your nose to “return to normal” after stopping oxymetazoline. Some people will only use it in one side of the nose each day, alternating sides for one day at a time, doing that over 3-4 days. This can improve your ability to breathe through your nose at night – at least one side, so you can sleep. Also consider using “hypertonic” nasal saline rinses to help decrease swelling of the nasal lining.
Best success! Not being able to breathe through your nose can be miserable.
